Banks of two, or banks of 10,000? Can their intensity be varied by
pulsing them on and off for various brief amounts of time, (so that
the flicker is not noticeable to the eye, or is this for a camera use,
where flicker will beat with the frame rate? Need details.

Need details.

In lieu of that: toggle switches and resistors.

Aha, exactly the type of application of which the much derided LED
